Esk Falls is a series of waterfalls and plunge pools on the River Esk in Upper Eskdale, within the Lake District, Cumbria. The river descends through multiple cascades before joining its first major tributary, Lingcove Beck, at nearby Lingcove Bridge.

The falls are set in remote, roadless countryside fed by streams draining off the Scafell range. The site is known for its striking water clarity, with pools ranging from pale aquamarine to deep emerald green.

A series of swimming holes extends along the falls, culminating in an upper waterfall reached by a short path from Lingcove Bridge.

The pools vary considerably in depth, and the surrounding landscape of wild fell country adds to the dramatic character of the location.
